EVERGREEN — The 16-year-old boy who shot two students and then himself at Evergreen High School [on September 10, 2025] appeared to espouse white supremacist views online and showed an interest in mass shooters in the days before the attack.
Social media accounts that appear to be connected to shooter Desmond Holly are littered with references to mass shootings and antisemitic views, The Denver Post found.
Jefferson County Sheriff’s Office spokeswoman Jacki Kelley on Thursday said Desmond had been “radicalized through an extremist network,” but declined to offer any additional details. The public accounts offer some insight into what that radicalization might have included.
In one photo posted on TikTok five days ago, Desmond appears to be wearing a black T-shirt with the word “Wrath” written in red across the chest — similar to what one of the attackers wore in the 1999 massacre at Columbine High School, also in Jefferson County. The same post also includes an image of the 15-year-old who killed two people and injured six more at a Madison, Wisconsin, school in December.
A post on X (formerly known as Twitter) about an hour before Wednesday’s attack shows an image of a hand holding a revolver — the type of weapon that authorities confirmed Desmond used during the attack. Representatives for the sheriff’s office did not answer specific questions about the social media accounts.
The accounts also include references to Holocaust denial, and the name of one of the accounts appeared to end with a reference to a prominent white supremacist slogan. That account reposted several videos showing school shooting scenes from movies, as well as another video that appeared to show the two Columbine shooters taking target shots at bowling pins. Other videos the account reposted were explicitly antisemitic or depicted people in [Axis] uniforms.
